Digispark is a development board based on the ATTINY85 microcontroller from ATMEL born in a successful campaign on Kickstarter.
Similar to the Arduino line , It is one of the smallest boards on the market.
Programmable directly from USB with the same Arduino tools. It has a built-in Micronucleus bootloader and can be replaced by similar ones such as the Trinket bootloader. Adafruit or others.
You can use many of the same Arduino libraries and have your own on the digispark wiki. Attiny85 Digispark USB Development Board features:
-USB power supply
-External power supply (7v-35v DC 12v maximum recommended)
-5V DC 500mA regulator on board
-Programmable with the Arduino IDE
-Loaded with Micronucleus bootloader

Welding Acid AG 35ml features:
Prepared transparent liquid, acidic, corrosive.
Prepares and facilitates welding on nickel-plated surfaces.
Apply a small amount of the preparation on the element to be welded, and then wash it with water. CAUTION:
Dangerous preparation, contains up to 35% phosphoric acid. In case of contact with skin or eyes, wash with plenty of water and consult a doctor. Keep closed and out of reach of children. It causes burns. Risk of serious eye damage.
